Even though Walter Isaacson's biography about late Apple co-founder Steve Jobs hit stores with a little more than two months left of 2011, it could end up being Amazon.com's top seller for the entire year.

The title, which was released today, became available for pre-ordering on Amazon's site in June, later jumping to the top of the charts following Jobs' death earlier this month. It's currently in the top spot in its hardcover and Kindle digital editions, as well as a recorded audiobook.

"The way things are trending, it could very likely be our top-selling book of the year," Amazon spokeswoman Brittany Turner told Reuters in a statement.

The book chronicles Jobs' life from beginning to end and is composed of some 40 interviews Isaacson had with Jobs, who authorized the project and had come to Isaacson, citing the author's ability to get people to talk. Isaacson also talked to friends, competitors, and colleagues to fill its 656 pages with an account of Jobs' life, both business and personal.

Originally planned to be released next year, the book's publishing date was moved up twice. Meanwhile, Jobs' took a medical leave from Apple in January, staying out of the public eye for much of this year as his health declined, adding extra intrigue to Isaacson's tale.

Citing an unnamed source, Reuters suggests the book was largely finished by the time the book was originally announced by publisher Simon & Schuster. Nevertheless, it was updated with details about Jobs' death by the time it went on sale.

Disclosure: "Steve Jobs" is published by Simon & Schuster, which like CNET is owned by CBS.
